PS Audio Power Plant Premier Power Cables

I swapped out my $150 heavy gauge cable for an AC-12 and found there to be no improvement. Should I move further up the cable foodchain to get the results you guys appear to be getting? I have been a PC sketic until the AC-12 finally delivered, but between wall and PPP (soon to be P5) it did not work.

All systems are different; I would think the AC-12 would be good enough to demonstrate a difference if you were going to get one. I have a Shunyata and swiching between different 20 amp PCs was like changing amps so it all dependes on the rest of the system, the quality of the AC and who knows what other factors.

I have the PPP. I use the PS Audio mid-range AC-5 cable. I needed quite a long length..which made the higher end AC-10 and AC-12's out of the question. IMO, going with a better cable than that is a waste of $$$.
Reason: The power is regenerated from scratch. Any pollution or whatever is removed when they reduce the incoming voltage, massage it and then re-amplify it for output. A 10 guage wire seems more than adequate to handle the power drain from components plugged into the PPP, including power amps as long as the maximum wattage capablity of the PPP is not exceeded (800 watt continuous output power).

I finally bit the bullet and tried a pair of the Shunyata Phyton CX between the wall and my now 2 P5's. Fully expecting to hear no improvoment over the cheap (but very heavy gauge) cords I am currently using, I sat back and listened. It took me all of 15 seconds into the first track I was playing to hear substantial improvement.

I'll refrain from trying to describe the difference and will just keep it at "better" across the board. These Shunyata's are definitely staying. By the way, these cables are suprisingly light - not a lot of copper for a cable listed at $1200. Not sure what their secret sauce is, but it works.

I am even intrigued by the idea of swapping out a few more. I have currently a mix synergistic precision AC (preamp), PS Audio AC-12's (source components) and Mojo XPC-7's (poweramps). Any suggestions on which cable(s) to substitute for another shunyata are welcome.
